WebTesting library
Hi, I don't know if this is of interest to anyone but I've created a webtesting library that is basically a phantomjs driver. It looks similar to Webdriver/Selenium but its in D. I have been using it to functionally test my web apps. If anyone is remotely interested I will publish it on dub. --Kingsley

I guess you are talking about https://github.com/kingsleyh/erik
?
Can you tell more about it. You write tests in D and "erik"
runs them with phantom.js?
Is something special when using it together with vibe.d?
Is there anything planed to put on top on it like behat?
Is it compatible with selenium. E.g. can you run tests in the
cloud or differnt browsers.
Sorry for asking maybe stupid questions.
Hey - yeah thats it.
I have been using d-unit to write the tests and using erik as the
tool to operate and drive the browser - in this case the
phantomjs headless javascript browser.
an example might be:
@Test
public void doit(){
Session session = Session.start(); // start new phantom on
random port
session.visitUrl("http://www.google.com;); // visit url
By search = By.cssSelector("input[name='q']");
session.waitFor(search, Condition.isClickable()); // wait
for search box to appear
WebElement searchBox = session.findElement(search); //
select search box
searchBox.sendKeys("d language kingsley");
// type into search box
writeln(searchBox.getAttribute("value")); // get
search box value
}
There is currently nothing special for vibe.d - however I'm
planning on doing some better integration there.
I may write a cucumber/behat/jbehave thing that it could hook into
It's currently not directly compatible with selenium - the hooks
exist but I haven't pushed them forward - but it would not be
hard to support selenium for driving different browsers.
I'm not 100% in which direction it will go at the moment as only
the basics are implemented.

The C variant is an mutable pointer to an immutable int. What is not to know about that? What foo() does not know is whether the original int is const or not: int i = 0; foo(i); // Can be mutated by the caller later on i = 1; For that reason, function foo() cannot store the pointer 'c' in confidence that it will not change in the future. Of course you and the dlang.org link that you have provided indicate that immutable is not the same as const. When you say You can qualify variables as immutable, which is similiar to C's const and Java's final, but it is transitive, it sounds like the main difference that brings 'immutable' is transitivity but I think the fact that data cannot be mutated is the main difference. That makes it possible for a function to request immutable data, something not possible in C because a const reference parameter is not a requirement but a promise not to mutate. And of course you never say they are the same; you say similar. Nothing is wrong with that. :) Ali This is excellent information on functional programming with D. I would love to see a lot more information in this area - perhaps a much longer article covering in more detail - and also covering what is missing - e.g. does D have a for comprehension, Option, Either etc

json parsing performance
I have read that std.json is pretty slow compared to other languages json parsers and I'm about to do a whole stack of json parsing and was wondering if anyone has got any benchmarks to indicate what slow means compared to other languages - particularly java, ruby, python? I want to know whether to roll up the sleeves and write my own json parser focused on performance or if slow just means a few ms slower - which I could live with.

I don't know much about json parsers so I can't say if it is a good one but it was subject to many discussions lately: https://github.com/kostya/benchmarks/tree/master/json great thanks. Hmm when I ran the test json I got a 212MB json file which the tests used. So although the std.json takes around 10 seconds to parse this - I can probably live with that and spend my energy getting on with my project. Of course it would have been nice to see the performance of std.json closer to that of rust and go instead of closer to ruby.
Business Venture in D - Help Wanted
Hi, I have a great idea for a small web based business and I want to build the system in D since I have committed to learning D this year. The idea builds upon technology in a space I have already had some experience in although everything is currently free - I want to completely re-write / revamp and monetise it. I am looking for a few people who are interested in helping me in this venture. Primarily I need some help with the D coding. Im only interested in people who can contribute time and effort and are reliable, quick to respond, easy to contact, enthusiastic, can suggest ideas as well. Ideally I want people that are willing to work for free in return for a share in the business. Only contact me if you are serious and have the qualities I listed above. kingsley dot hendrickse at gmail dot com

I got hooked on the Apple ][ version (http://corewar.co.uk/robotwar/) back in the 80's and started a version for the Amiga called Tonks but it never got off the drawing board. I've always loved this game concept. Even did a version to run each tank on a node of an Intel Hypercube as a school project. Cool - feel free to give me any feedback. At the London D programmers meetup we had a tank tournament which was great fun. Some of the guys who came had not done D before - they were Scala / Java guys - but really enjoyed playing with D by way of the tanks game. Great fun was had by all there. Thanks to Kingsley for organizing this, and perhaps more importantly, getting the framework together. An interesting point was made by some there: this looks very like Java coding. Laeeth and I both agreed, saying that we felt Kingsley background in Java was being reflected a little in the look and feel of the D code, that if a C++ programmer had written it most likely the code would have had a C++ feel to it. Much of this is about spacing, identifier structure and things like that – relatively trivial stuff in the main. The question us then is this fine ( that D code can have a Java or C++ feel) or should there always be a D feel to all D code? There should be a video of the tournament emerging at some point from SkillsMatter who sponsor the meetup as they filmed it. The video may not reflect quite as much of the fun that was had!

By default FP litterals are double...IIRC float oneDegree = (PI / 180.0f); float first = -(oneDegree * 10.0f); float second = (oneDegree * 10.0f); float step = 0.01f; float[] r = iota(first,second,step).array; writeln(r); float item = 0.174531f; writeln(r.canFind(item)); Adding the f still produces a false result. Also I tried changing all to double but still not working - I always get false back. Interestingly if I harcode the output of the iota into an array - then things start to work as I expect.
Re: Are there any 2D games libraries available for D2?
I'm using DSFML and it is one of the easiest. Though I had strange issues like high ram usage and text not rendering. Though the ease of use and performance is phenomenal. Thanks for the heads up. I'll open an issue to inspect RAM usage, but can you let me know when you were having Text rendering issues so I can inspect that too? This link can give you more information about it: http://en.sfml-dev.org/forums/index.php?topic=17550.0 I started getting text rendering issues when I was playing with my space background render textures. It's kinda strange cause they seem unrelated. I'll check it out, thanks! Hi - I started using dsfml - I really like it! The fact that there were pre-built zips to download for my platform was awesome!! Got started straight away. I have been googling but not found a nice answer. I want to make an explosion from a list of 20 images. sfml doesn't seem to have very good support for doing that kind of thing. I have seen an external thing called thor - but I guess I'd have to port that to D - maybe a bit beyond my skills at the moment. If anyone has an example of creating an explosion from images using dsfml please post it so I can learn :) :) you will see why I need this pretty soon :) --K

The next goal would be to adapt the webpage and the installation chapter and to re-register the domain dgame.dev.de After that (and after my hopefully successful exams) I will rebuild Dgame from scratch with the goal of a more consistent and better structure and with the idea in mind to use @nogc wherever possible. Awesome!! great news :)
Reloaded for dub
Hi Just thought I would share this in case anyone else finds it useful. I wrote a tiny utility that detects changes to D files and then rebuilds and re-executes the main binary using dub. I use for developing with vibe.d and other dub D project that have an executable binary. The code is here: https://github.com/kingsleyh/reloaded essentially you just run dub in the root and it builds the reloaded binary. Then you just copy that binary to the root of your dub project and ./reloaded and then as soon as you make a change to a D file your code will be built and executed. --K

Re: London D Programmers MeetUp
Thanks to everyone who attended it was a great evening of D fun :) As part of the evening we did a secret santa code challenge - here are some of the results: http://www.meetup.com/London-D-Programmers/messages/boards/thread/48694585 We had about 13 people from different backgrounds - many from C/C++ as well as Java, F# and dynamic languages such as Python. Many of the guys had a financial / banking background or an academic background - for example we had some guys working on market data, another guy who ran a hedge fun as well as people from scientific / research and university backgrounds. We touched on IDE's and editors for D - I demo'd my intellij plugin. Bruno was also there (he maintains the eclipse D plugin DDT) and he had some interesting things to say about where he thought the future of IDE's is going especially in terms of code completion. In my intellij plugin I actually re-use the guts of the DDT parser/lexer and the general opinion seemed to be that have a single set of tools that could be re-used in multiple IDE projects was a good way forward. I already implemented Brian's DCD and DScanner tools in my plugin and Bruno was looking to go that way also rather than re-writing the wheel each time. Brian certainly has some great tools in D for this kind of thing. (Hackerpilot - DCD/libdparse/DScanner etc) We also had some discussion about the popularity of D - and many felt that D was a great language especially coming from C/C++ but that the whole community was perhaps a little fragmented and finding information on the Dlang site was also a bit disjointed and that in order for a language to gain popularity it needed the appropriate community support and information - the recent language Rust was mentioned as having great documentation/support for new people and is arguably doing a better job at that aspect than D especially since its such a new language compared to D. There was also a bit of discussion around the dub package manager with Russel W feeling strongly that dub was more like a java maven and had many issues for what he wanted to do. I think he has since posted something on the D forum about his dub feelings. We got onto dub from my intellij plugin which uses dub by default. We got together in pairs with 1 more experienced D person and 1 newbie / less experienced D persons and paired on the secret santa challenge. We only had about 45 mins for this one and then some discussion on how we chose to implement things. A couple of issues came out of the challenge regarding familiarity with syntax and then spending time hunting down the docs - is there a forall in D?

Hi guys, I have been working on an intellij plugin which is here: https://github.com/kingsleyh/DLanguage I only started learning D a couple of weeks ago and I haven't written an intellij plugin before - and also I'm not very familiar with parsing/lexing. On my first pass - I got all the infrastructure working - e.g. run configurations, project creation, file creation etc. And I'm working on a BNF and JFlex by hand - but I realise it will take some time - so I have a branch which implements the DDT parser/lexer so I could get something working while I work on the bnf - however it breaks the contextual run configurations - which is pretty much essential for the plugin to be useful. I'd like to get the DDT parser/lexer working but I'm not really sure where to go from where I am now. My DDT branch is called with_ddt. If anyone has any pointers to what I need to do next that would be very helpful - even in terms of reading or reference material. I guess it all comes down to the DParserDefinition class - as my master branch uses a FlexAdapter which gives access to the context. But in the with_ddt branch its just using the DParser - which I think needs to have the hooks into the AST tree implemented or something like that. Anyway let me know if you have any pointers or offers of help :) --K Actually I guess what I need is a way to make the PSI structure. I'm not sure how I would do that with the DDT code I have imported. I've sent you an email reguarding my own work on getting a plugin together using Dscanner. As well as the source code. Feel free to use it. I've successfully integrated the Psi generation stuff with the DDT parser/lexer now with a huge thanks to Rikki. So now I think I can add all the other ps related stuff - code insight, refactoring, completion etc etc Of course its the first cut - so I'll have to do some code cleanup once I understand what I'm doing! Thanks for your help and support :)

See: https://github.com/Hackerpilot/DGrammar An interesting path to take for an intellij plugin would be to use his DCD/libdparse for all the heavy lifting, with the plugin just farming out the work to external daemon process(es). That would avoid having yet another lexer/parser implementation to keep up to date. I actually forked yours originally to get it running in IDEA 14, then decided to mess with the lexer since it was causing some problems and went off from there. I saw it was somewhat inactive and tried contacting you, but couldn't find any of your contact info anywhere! Glad to see you turned up here. Hi guys, I have been working on an intellij plugin which is here: https://github.com/kingsleyh/DLanguage I only started learning D a couple of weeks ago and I haven't written an intellij plugin before - and also I'm not very familiar with parsing/lexing. On my first pass - I got all the infrastructure working - e.g. run configurations, project creation, file creation etc. And I'm working on a BNF and JFlex by hand - but I realise it will take some time - so I have a branch which implements the DDT parser/lexer so I could get something working while I work on the bnf - however it breaks the contextual run configurations - which is pretty much essential for the plugin to be useful. I'd like to get the DDT parser/lexer working but I'm not really sure where to go from where I am now. My DDT branch is called with_ddt. If anyone has any pointers to what I need to do next that would be very helpful - even in terms of reading or reference material. I guess it all comes down to the DParserDefinition class - as my master branch uses a FlexAdapter which gives access to the context. But in the with_ddt branch its just using the DParser - which I think needs to have the hooks into the AST tree implemented or something like that. Anyway let me know if you have any pointers or offers of help :) --K Actually I guess what I need is a way to make the PSI structure. I'm not sure how I would do that with the DDT code I have imported. I've sent you an email reguarding my own work on getting a plugin together using Dscanner. As well as the source code. Feel free to use it. I've successfully integrated the Psi generation stuff with the DDT parser/lexer now with a huge thanks to Rikki. So now I think I can add all the other ps related stuff - code insight, refactoring, completion etc etc Of course its the first cut - so I'll have to do some code cleanup once I understand what I'm doing! Thanks for your help and support :) Also, if you have questions about the DDT parser/lexer, or if there are changes that might help your project, let me know, I'll be glad to add such changes (assuming they also fit well with the way DDT uses the parser/lexer). Hi Bruno, Thanks very much. I do have a couple of questions about DDT in relation to my plugin. Firstly - I'm not too familiar with parsing/lexing but at the moment the Psi Structure I have implemented that comes from the DDT parser/lexer is not in any kind of hierarchy. All the PsiElements are available but all at the same level. Is this how the DDT parser works? Or is it down to my implementation of the Parser/Lexer that wraps it to create some hierarchy. For intellij it's going to be vastly easier to have a hierarchy with nested elements in order to get hold of a structure representing a class or a function for example - in order to do things like get the start and end lines of a class definition in order to apply code folding and to use for searching for classes and stuff. Secondly - how active it the development of DDT - does it keep up with the D2 releases. --Kingsley

I've still got some experimentation to do. On the plus side I implemented commenting, code folding but everything else needs a psi hierarchy
